Got your RFQ in this morning and we've been running these DY-C501 units for about eight months now—pretty happy with the consistency across batches, honestly.
Teh 1064nm cuts through dark inks fast, though if you're mainly treating reds and oranges you'll lean on the 532nm more, and the 1320nm is there for deeper pigment work or skin tightening on lighter Fitzpatrick types.
Peak energy hits 1500mJ but most buyers actually run it between 600-800mJ for routine tattoo removal, just because the lower setting reduces bruising and recovery time for clients (usually 2-4 weeks between sessions).
One thing we didn't expect was how much the water circulation plus dual fans matters in back-to-back treatments—without that cooling, unit would thermal-throttle after 8-10 passes, but it handles full days pretty well.
Lead time usually is about 20 days or so form order, and they ship with CE and patent certs included in the box; we've had two units arrive and both fired up right on AC110V without any hiccups.
